Common Antibiotic May Reduce Schizophrenia Risk in Teenagers, Study Suggests
A widely used antibiotic could play a surprising role in lowering the risk of schizophrenia among young people, according to new research published in the American Journal of Psychiatry.
The study found that teenagers who were prescribed doxycycline, a common antibiotic used to treat infections and acne, were 30 to 35 percent less likely to develop schizophrenia in adulthood than those treated with other antibiotics. Researchers described the findings as “tentative but exciting,” emphasising that while the results are promising, more research is needed to confirm them.
Schizophrenia affects around 23 million people globally and typically develops in early adulthood. The condition is characterised by hallucinations, delusional thinking, and cognitive difficulties, which can significantly disrupt daily life. While medication and therapy can help manage symptoms, there is currently no cure.
The Finnish study examined health records from more than 56,000 adolescents who had received mental health treatment. Of these, about 16,000 were prescribed doxycycline. The results showed a notable difference in schizophrenia diagnoses later in life, suggesting that the antibiotic might offer some level of protection.
Although the study was observational and cannot prove that doxycycline directly prevents schizophrenia, researchers believe the link may be tied to how the drug reduces inflammation in the brain. Doxycycline is known to have anti-inflammatory properties, and inflammation has been increasingly linked to psychiatric disorders.
The team also pointed to another possible mechanism: synaptic pruning. This is a natural process in which the brain eliminates unnecessary neurons and synapses during adolescence. When pruning occurs abnormally, it has been associated with schizophrenia. The researchers suggest doxycycline may influence this process in a beneficial way.
“This is an important signal to further investigate the protective effect of doxycycline and other anti-inflammatory treatments in adolescent psychiatry patients,” said Ian Kelleher, the study’s lead author and a professor of child and adolescent psychiatry at the University of Edinburgh. He added that the approach “could potentially reduce the risk of developing severe mental illness in adulthood.”
However, experts not involved in the study urged caution. Dominic Oliver, a psychiatry researcher at the University of Oxford, noted that “many other treatments have shown early promise and have ultimately shown not to be effective in large-scale trials.”
Dr Katharina Schmack, a psychosis researcher at The Francis Crick Institute in London, said that while the findings were statistically significant, “the absolute numbers are modest.” She explained that after doxycycline treatment, instead of five out of 100 people developing schizophrenia, the figure would drop to about two or three.
Both experts agreed that the research opens a valuable avenue for further investigation into how inflammation and brain development affect schizophrenia risk. As Schmack put it, “Uncovering clinical associations in studies like this is important because this can direct further biological investigations.”

Global Mental Health Cases Near 1.2 Billion as Anxiety and Depression Drive Sharp Worldwide Rise
A major global analysis has found that mental health conditions have surged to an estimated 1.2 billion people worldwide, driven largely by steep increases in anxiety and depression over the past three decades.
The findings, published in The Lancet as part of the Global Burden of Disease Study 2023, show that the number of people living with mental disorders has almost doubled since 1990, marking a 95% rise. Researchers say major depressive disorder and anxiety disorders have seen even sharper growth, increasing by 131% and 158% respectively, making them the most prevalent mental health conditions globally.
The report describes mental illnesses as widespread conditions that create long-term disability and significant human suffering. It also highlights broader consequences for economies and public services, including reduced productivity, lower workforce participation and increasing pressure on health and welfare systems.
Researchers estimate that in 2023 alone, around 620 million females and 552 million males were affected by mental health conditions. While the overall burden is rising across both sexes, the study points to notable differences in the types and prevalence of disorders.
Among women, depression and anxiety were the most commonly reported conditions, alongside higher rates of eating disorders such as anorexia nervosa and bulimia nervosa. The report links this disparity to a mix of biological, social and structural factors, including exposure to domestic violence, sexual abuse, gender inequality and reproductive health-related changes.
In contrast, neurodevelopmental and behavioural disorders, including attention deficit hyperactivity disorder (ADHD), conduct disorder and autism spectrum conditions, were more frequently diagnosed in men.
Teenagers aged 15 to 19 were identified as the group experiencing the highest mental health burden globally, raising concerns about early onset of conditions and insufficient preventive care for young people.
The study identifies several key risk factors associated with mental illness, including childhood sexual violence, bullying and intimate partner violence. These factors are strongly linked to conditions such as depression, schizophrenia, bipolar disorder and anxiety disorders. However, researchers note that such exposures have remained relatively stable over time and account for only a portion of the overall rise.
According to the authors, broader drivers are likely contributing to the increasing prevalence of mental disorders. These include genetic and biological influences, poverty, inequality, and the growing impact of global crises such as armed conflict, pandemics, natural disasters and climate-related stress.
While mental health conditions have long been a leading cause of disability worldwide, the report warns that the situation is worsening. At the same time, health systems have not expanded services at a pace matching demand.
The authors caution that the gap between rising need and limited access to care is becoming more pronounced, leaving millions without adequate treatment or support.
